A wooden backboard is recommended for all installations and must be installed when the location has masonry or 
plasterboard walls. A  ½  inch plywood material is sufficient for most installations. The back-board should be mounted at 
a convenient height, about 1 meter above the floor, and be bolted in two number of places to distribute the weight of the 
system. 
 
 
 

 
Once the equipment installation site has been identified and a dedicated earth ground, and lighting and ventilation are 
available, verify that all equipment required are on-site and have not been damaged during shipment. Assure there is no 
shipping damage. Note that a mounting template is packed with KSU and this template will be required later in the 
installation. Check that the type and quantity of boards received is correct and optional equipment are on-site.   
 
If any equipment is damaged or missing, notify appropriate personnel to correct the situation.
